https://forums.autodesk.com/t5/inventor-forum/drawing-centered-pattern/m-p/10713840#M93232 <P>In the drawing view attached I want to show the circular centre line through a pattern of 4 holes on a 100mm PCD. My problem is that I don't have a circular feature to select as the centre of the pattern. I tried using the origin axis but that does not work. I eventually created a sketch with a tangent circle in the small square feature, created the PCD circle then, made the sketch circle invisible. Is there an easier way to do this?</P> Tue, 26 Oct 2021 09:26:43 GMT NigelHay 2021-10-26T09:26:43Z https://forums.autodesk.com/t5/inventor-forum/drawing-centered-pattern/m-p/10713840#M93232 <P>In the drawing view attached I want to show the circular centre line through a pattern of 4 holes on a 100mm PCD.

So start centerline, select hole1, hole 2, hole 3, hole4 and hole 1, RMB click create.</P><P>&nbsp;</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="theobot_0-1635249569785.png" style="width: 400px;"><img src="https://forums.autodesk.com/t5/image/serverpage/image-id/981806i30A54CFCA4CF2F00/image-size/medium?v=v2&amp;px=400" role="button" title="theobot_0-1635249569785.png" alt="theobot_0-1635249569785.png" /></span></P><P>&nbsp;</P> Tue, 26 Oct 2021 12:00:16 GMT https://forums.autodesk.com/t5/inventor-forum/drawing-centered-pattern/m-p/10714198#M93233 theo.bot 2021-10-26T12:00:16Z https://forums.autodesk.com/t5/inventor-forum/drawing-centered-pattern/m-p/10714254#M93234 <P>No, that does not work. The first selection defines the centre of the pattern, if I select the first hole, Inventor wants to create a pattern centred on that hole.</P> Tue, 26 Oct 2021 12:23:50 GMT https://forums.autodesk.com/t5/inventor-forum/drawing-centered-pattern/m-p/10714254#M93234 NigelHay 2021-10-26T12:23:50Z https://forums.autodesk.com/t5/inventor-forum/drawing-centered-pattern/m-p/10714268#M93235 <P>Are you sure you used "centerline" and not " centered Pattern"</P><P>&nbsp;</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="theobot_0-1635251169906.png" style="width: 400px;"><img src="https://forums.autodesk.com/t5/image/serverpage/image-id/981825iC60C18BBB0295760/image-size/medium?v=v2&amp;px=400" role="button" title="theobot_0-1635251169906.png" alt="theobot_0-1635251169906.png" /></span></P><P>&nbsp;</P> Tue, 26 Oct 2021 12:26:37 GMT https://forums.autodesk.com/t5/inventor-forum/drawing-centered-pattern/m-p/10714268#M93235 theo.bot 2021-10-26T12:26:37Z https://forums.autodesk.com/t5/inventor-forum/drawing-centered-pattern/m-p/10714325#M93236 <P>OK, got it now. I've always used centred pattern for this before, never tried using centreline.
